1'0 a/ZZ it may concern: I l Be it known that I, HENRY 'NIOHOLSBURG,

, a citizen'of theUnited States, residing at New hose; 'and'the object/{thereof v p a chamberilg 'whichfiselliptical in longitu- 4,

apparatus, as a lawn-sprinkler, other or similar purpose.

York, in the county of New York and State of New York, have invented certain" new and useful Improvements in Nozzles, ofjwhi'ch the following is a full and complete specification,

such as will enable those skilled in the art'to which it appertains to make and use the sa, me,= This invention relates to nozzles such as are usually employed in "connection with; waterguishin g or for any The inye'ntion is fully disclosed in the hi1- lowing specification, elf-which the acoompanying drawings form a part, in whiche- Figure 1 is-a central longitudinal section of my improved nozzle; Fig. 2, a section on the line 2 2 thereof; Fig. 3, a side view of a detail of the construction which is shown in Fig. 2; Fig. 4, a longitudinal section of one form of, adischarge-nozzle which I employ,

, and Fig.'5 a similar view of a modified form of construction.

. In the drawings forming fication, Ii ent are part of this specithe separate parts of my improvedesignated by the same numerals of rfiference in each of the views, and in the p {actic'e of my invention I provide a nozzle t'qf the purpose herein specified which comhead 7, by means of wetor-hose, or this-head 7 may be formed in any desired manner, and adjacent thereto is an enflarged bbdy portion 8, in which is formed dinal section-and at the end of which is a reduced extension 10, theeendiof which is I digchargenozzle shown in Fig. is intended scgeywthreaded, as shown-and 1, and adapted to receive a discharge-nozzle, 12, which is shown in Fig. 4.- and a modification of which is shownin Fig. 5. v

. The discharge-nozzle12 isintended to throw the water in a solid stream,

outer end of which is smaller than the inner end, as shown at14, while the form of the the nozzle is titio-ngflate thecentral portion 21 of which 5 horizontally of'sa'id "chamber and is provided with a central circular opening 22,

' wardly,

the screwthreaded plug 24 is an annularpassing centrally and-is preferably. provided with a. longitudinal bore 13, the

- tubular chamber to throwthe water in a circular spray, and

- consists of a screw-threaded shank 15, on

whichl is formed an enlarged central portion 16,'which is provided ,with a bell-shaped or flaring mouth-17, at the base ofwhich is an inwardly-directed 'annularflange or rim 18, and secured transversely of the enlarged portion 16 is a bar to which is secured-a disk 20,- which is elliptical in cross-section, and whichis 'adapted to partially close the open"- ing within ,the flange or rim 18, said disk 20 being outside of the inner edge of said'flange or rim "and being of slightly-greater diameter thansa'id. opening. V .p i

The chamber 9 in "the enlarged body 8 of provided with an angular parexteri and one side of said body portion 8 of the nozzle in line with the central opening 22 in the partition-plate is provided with a circular opening 23, which is closed by a screw threaded plug 24:, which is provided'with an enlarged semicircular'head 25, in which is formed a central cavity 26, which opens inand formed in the upper surface of chamber 27, in which is placeda spiral spring 28, and that side of thebody portion 8 of the nozzle opposite the opening 28 is provided with an inwardly-directed tubular casing 29., whereby a tubular chamber 30is formed, and through the opening 22 in the par'titiomplate 21 and through the bottom of the casing 29 is a shaft 31, the lower end of which is reduced in size and enters the shaft below the partition-plate 21 is a valve composed of a disk or plate 33, above which cavity 26 in the plug 24, and mounted on said is placed a washer 34, which may be composed of any. suitable material and which is adapted to serve as a valve to close the openkv ing 22, and the disk or plate 33, which is secured to the shaft 31, or the lower end thereof, re'stson the spring 28, and said spring is adapted to force said shaft upwardly, so as to close the opening 22. p

Placed in the chamber 30, through which the, shaft 31 passes, is a packing 35, and said 30- is closed by a screwthreaded plug 30, through which the shaft 31 also passes, and the upper end of said screwthreaded plug is enlarged and cylindrical in form, as shown at 37, and above said enlarged central portionfis an annular flange or rim 3S, and formed in one side of the cylindrical portion is a transverseslot or groove 39, in which is pivoted a lever -10, which is operated by a spring 11, and the shaft 31 is provided with an annular groove 42, which is adapted to receive said lever, or the ir; ner end thereof, when said shaft is in its lowest position, and mounted on or secured to the upper end of said shaft is a knob or handle -13.

The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

In the normal position of the parts or when the nozzle is not in operation the opening 22 in the partition-plate 21 is closed by the valveon the shaft 31, the spring 28 forcing the shaft upwardly to produce this result, and whenever it is desired to operate the nozzle. theshaft 31 is forced inwardly and the springoperated lever 40 enters the annular groove 22 in said shaft and the water is free to flow through the nozzle, and whenever it is desired to cutoff the (low of the waterthe outer end of the lever 10 is forced inwardly, so as to release the inner end thereof from the annu- .lar groove 42 in the shaft 31, when the spring 28 will force said shaft outwardly and close the opening 92 in the partition-plate 21.

\Vhcn the nozzle shown in Fig. 5 is in use, the water passes between the disk 20 and the inwardly-directed annular flange or rim 18, and as the raid disk is slightly larger than the opening in said nozzle the water passes out in a ve y thin sheet all around said disk and is turned baclrwardly by the hell-shaped month of the nozzle toward the center and produces a very tine effect owing to this peculiar construction of the nozz e and disk.

This device is simple in construction and operation and is perfectly adapted to accomplish the result for which it is intended, and it will be apparent that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages. Having fully described my invention, I claim as new and desire to secure by Letters Patent" 1. A water-nozzle, comprising a body portion, in which is formed an enlarged chamber and one end of which is provided with means for securing it toa flexible tube or pipe, and

the other end with an extension to which the.

discharge-nozzle proper is secured, said chamber being provided centrally thereof, with a longittuliual partit ion-plate which is provided with a central opening through which passes a spring-operated shaft which is provided with a valve which is adapted to close said opening, said shaft being projected through an opening in said chamber at one side thereof, which is closed by a screw-threaded plug, in which is formed a transverse slot or groove, in which is mounted a spring-operated lever, and said sh aft being provided with an annular groove in connection with which said lever operates, substantially as shown and described.

2. A nozzle, comprising an enlarged body portion, at one end of which is a hcad' by means of which the nozzle maybe connected with a tube or pipe, the other end of said body portion being provided with an extension adapted to receive a discharge-nozzle proper, said enlarged body portion being provided with a chamber, in which is a partition- .plate provided with a central. opening, said body portion bein also provided at one side with an opening which is closed by a screwthreaded plug in which is formed a cavity or recess, and at the opposite side with a tuhular inwardlyalirected. casing, and a springoperated shaft passing through said chamber, one end of which enters the cavity or recess in said screw-threaded plug, and the other end of which passes through said tubular casing, and through a screw-threaded plug mounted therein, said last-named screwthreaded plug being provided at one side with a transverse slot or groove in which is placed a spring-operated lever, and said shaft being provided with an annular groove in connection with which said lever operates, and with a valve by which the opening in the partitionplate is closed, substantially as shown and described.

3. A discharge-nozzle, comprising an en larged portion 16, bell-shapedmonth17, flange 18, bar 19 and disk 20, substantiallyas and for the purpose set forth.

t. A nozzle providedwith an enlarged body portion, in which is formed a partition which is provided with a central opening,and a transversely-movablespring-opcratcd shaft which is provided with a "valve adapted to close said opening, and means for locking said shaft and said valve in an opening position, consisting of a screw threaded plug mounted in one side of the body portion of the nozzle through which said shaft passes, said plug being propyided with a spring-operated lever, and said :ffshaft with a groove in which said lever opergates, substantially as shown and described.
